dstat系统资源检测工具，可以统计的数据包括

Java代码

OPTIONS

-c, --cpu

enable cpu stats (system, user, idle, wait, hardware interrupt, software interrupt)

-C 0,3,total

include cpu0, cpu3 and total (when using -c/--cpu)

-d, --disk

enable disk stats (read, write)

-D total,hda

include total and hda (when using -d/--disk)

-g, --page

enable page stats (page in, page out)

-i, --int

enable interrupt stats

-I 5,10

include interrupt 5 and 10 (when using -i/--int)

-l, --load

enable load average stats (1 min, 5 mins, 15mins)

-m, --mem

enable memory stats (used, buffers, cache, free)

-n, --net

enable network stats (receive, send)

-N eth1,total

include eth1 and total (when using -n/--net)

-p, --proc

enable process stats (runnable, uninterruptible, new)

-r, --io

enable I/O request stats (read, write requests)

-s, --swap

enable swap stats (used, free)

-S swap1,total

include swap1 and total (when using -s/--swap)

-t, --time

enable time/date output

-T, --epoch

enable time counter (seconds since epoch)

-y, --sys

enable system stats (interrupts, context switches)

--aio enable aio stats (asynchronous I/O)

--fs enable filesystem stats (open files, inodes)

--ipc enable ipc stats (message queue, semaphores, shared memory)

--lock enable file lock stats (posix, flock, read, write)

--raw enable raw stats (raw sockets)

--socket

enable socket stats (total, tcp, udp, raw, ip-fragments)

--tcp enable tcp stats (listen, established, syn, time_wait, close)

--udp enable udp stats (listen, active)

--unix enable unix stats (datagram, stream, listen, active)

--vm enable vm stats (hard pagefaults, soft pagefaults, allocated, free)

--plugin-name

enable (external) plugins by plugin name, see PLUGINS for options

Possible internal stats are

aio, cpu, cpu24, disk, disk24, disk24old, epoch, fs, int, int24, io, ipc, load, lock, mem, net, page, page24, proc, raw,

socket, swap, swapold, sys, tcp, time, udp, unix, vm

--list list the internal and external plugin names

-a, --all

equals -cdngy (default)

-f, --full

expand -C, -D, -I, -N and -S discovery lists

-v, --vmstat

equals -pmgdsc -D total

--float

force float values on screen (mutual exclusive with --integer)

--integer

force integer values on screen (mutual exclusive with --float)

--bw, --blackonwhite

change colors for white background terminal

--nocolor

disable colors (implies --noupdate)

--noheaders

disable repetitive headers

--noupdate

disable intermediate updates when delay > 1

--output file

write CSV output to file

--profile

show profiling statistics when exiting dstat

ifstat是统计所有网卡的输入输出流量的。

vmstat主要统计的就是内存的使用情况了。

iostat统计的就是硬盘的读写情况。
